ABSTRACT:
A digital complex correlator for a band-spread communication system having a variable correlation length wherein first and second channel input data are multiplied by first and second channel reference data in a multiplier to produce multiplication data. The multiplication data is then accumulated in an accumulator and the outputs from the accumulator are applied to an adder and squaring circuit via a correlation length control circuit.
